A complete set of original engineering drawings for the iconic DeLorean DMC-12 sports car - made famous in the Back to the Future film franchise - is for sale on internet auction site eBay for a jaw-dropping £10,000.

The sell-off of the collection, which was once kept in the car maker’s purchasing office in Coventry, is being described as “a totally unique opportunity to acquire a car full of original blueprint copies of the legendary DeLorean gull wing sports car”.

The collection is being offered by seller dangerturtle who is based in Norfolk at a ‘buy it now’ price of £10,000.

It contains both original pen drawings and copies on either film or paper and a set known as ‘secondary masters’ which divide the car up into sections.

The seller reveals he bought the drawings around 20 years ago from a neighbour who found them in the loft of a house he had just bought in Norfolk.

The location might lead to the supposition the drawings formerly belonged to Norfolk-based Lotus, who engineered the DMC-12, but it has been revealed the drawings were formerly kept in Coventry.

Just how they ended up in Norfolk was explained to the Telegraph by former DeLorean managing director Barrie Wills, who now lives in Meriden.

He said: “The DeLorean production purchasing department was one of the first occupiers of Christchurch House in Coventry city centre.

“It was headed up by Nick Sutton, who was the purchasing manager.

“To enable them to do their work they had a complete set of secondary masters in order to sent out copies to prospective suppliers.

“There were three sets altogether, one in Dunmurry in Northern Ireland and another at Lotus in Norfolk.”

Mr Wills, who is originally from Coventry, said he returned to the Coventry office for a ‘wake’ on November 5 1982, days after DeLorean founder John DeLorean was arrested in an FBI drugs sting in Los Angeles.

“I left Belfast and flew in, the Coventry office was holding a kind of wake.

“They had cleared the place out pretty well - the receivers had said get rid of all the paperwork - whatever we can’t sell then dump.

“Nick and I talked about the set of secondary masters. We thought maybe one day the company might be resurrected and wouldn’t it be useful.

“I said to Nick don’t throw those away.

“Nick took all those drawings with him. He lived in Hinckley at the time and put them in his loft.

“They stayed there until three years later when he was hired by Lotus in Norfolk.

“He was there for about ten years when he got a job in Northern Ireland.

“When he moved he thought ‘I’m not clearing the loft out again, I will just leave the master drawings there’.”

The drawings have yet to be sold on eBay but there are quite a few people watching the sale and some have enquired whether they could buy individual items.

The seller has replied to say he does not want to split the collection up, though a number of people have suggested the collection could be worth a lot more if sold bit by bit.

One wrote: “Only £10,000? You have gold in your hands and you are giving away.... Never below £50,000....”

As to what the collection might be worth Mr Wills, was the company’s longest serving employee and its final chief executive, isn’t sure.
